摘　　要：针对摇摆墙的特殊性能要求使其在工程运用中陷入施工工艺、摇摆幅度和成本控制等方面的困局,综合经济效益、施工方便、震后易更换等理念,发明了一种连接框架与摇摆墙的耗能连接装置以及摇摆墙摇摆可控的铰支座;基于此,利用摇摆墙结构的构造优势以及被动控制技术的减震原理,提出了一种新型的钢筋混凝土(reinforced concrete,RC)框架-摇摆墙式减震结构。为研究该结构的抗震性能,设计了缩尺比例为1/10的6层框架结构和框架-摇摆墙式减震结构,通过振动台试验研究这2种结构模型在不同地震作用下的动力特性、加速度反应、位移反应,描述了模型结构的破坏模式以及抗震性能。结果表明,摇摆墙式减震系统能够有效消耗地震输入能量,衰减结构的动力响应,使结构最大加速度峰值和最大位移峰值降低率分别达到36%和20.15%,而且能够利用被动减震的原理有效抑制主结构的振动,改善框架结构的侧向变形模式,延缓结构的损伤进程,提高结构的整体抗震能力。In view of the special performance requirements of the rocking wall,the rocking wall structure is often trapped in the dilemma of construction technology,rocking range and cost control in engineering application.Based on the concepts of economic benefits,convenient construction,and easy replacement after earthquake,an energy-consuming connection device between the frame and the rocking wall was developed.Additionally,a hinge support with controllable swing of the rocking wall was also designed for the test models.Thus,a new type of reinforced concrete(RC)frame-rocking wall damping structure is proposed by loveraging the structural advantages of the rocking wall structures and the principle of passive control technology.Then,1/10 scale shaking table tests of six-story RC frame structure and RC frame-rocking damping wall were conducted to verify the effectiveness of the structure.The dynamic characteristics,acceleration response,and displacement response of the test models under different earthquakes were studied by shaking table tests.The failure mode and seismic performance of the test models were also described.The results show that the rocking wall damping system can effectively consume seismic input energy and attenuate structural dynamic response,reducing the maximum peak acceleration and the maximum peak displacement of the structure by 36%and 20.15%,respectively.Moreover,the rocking wall damping structure can also effectively suppress the vibration of the main structure by using the principle of passive damping,improving the lateral deformation mode of the frame structure.Additionally the damage process of the structure is delayed,enhanced the overall seismic capacity of the structure.
